Be it known that I, VINCENT C. TILLIER, a citizen of France,` residingat Flint, county of Genesee, State of-Michigau. have invented a certain new and useful Improvement. in Battery-Connecter Removers; and declare the following to be a full, clear, and exact discription of the same, such as will enable others skilled in theart to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improved battery or terminal removing tool.

An object is to provide an improved elfective tool for the purpose sct forth, which tool is easily operable and through the use of which it is possible to quickly remove a battery terminal or connecter from a battery ost.

p A further object is to provide a tool having a pair of easily operable handles by means of which a pair of gripping jaws are retracted relative a fulcrum member so .that when it is desired to remove an encircling part such as a battery connecter from a battery post or a gear from a shaft, the jaws may be engaged over the part to be removed and the fulcrum member placed against the stationary post or shaft from which the part is to be removed and the jaws retracted by the operation of the handles, thereby withdrawing said encircling part.

The above and other objects together with details of construction and operation will more fully appear from the following description, appended claims and accompanying drawings, in which:

Figure 1 is an elevation showing my tool applied to the removal of a battery terminal of a battery post.

Fig. 2 is a side elevation of my improved tool.

Fig. 3 is a cross-sectional View taken on the line 3-8 of Fig. 1.

My invention as here shown is particularly intended for use as a tool to be used in the removal of a battery connecter or terminal from its supporting post. It obviously might be employed to withdraw a lgear from a shaft or some other small encircling part from' its supporting member'. Battery terminal connecters, however, after being in use for some time become securely xed to the supporting post upon which they are mounted and their removal is attended with considerable diiiculty. Through the use of i my improved tool it is possible to quickly and easily withdraw the connecter from its supporting post.

In the drawing, let 5 indicate the batter)` post and 6 a connecter mounted upon the post. The tool comprises a pair of opposed jaws 7 turned over at the ends as at 8 to grip underneath the connecter 6. These jaws are connected together at their opposite. end by a toggle, comprising links 9, one pivoted to each jaw and pivoted together in the center as at 10. Pivotally supported between these links is a fulcrum plunger 11 which extends forwardly from the pivotal connection between the jaws.

I provide a pair of operating handles 12 which cross each other and are pivoted together as at 13, which perating handles are pivoted to the jaws, one to each jaw as at 14. The pivotal connect-ion of the' handles with the grippingaws is forwardly of the toggle connection between the jaws.4 I provide a spring 15, one end of which is connected to the plunger 11, the other end to a fixed plate 16 which is disposed between the handles 12 at their pivotal connection.v I provide this plate 16 in order that there may be sufficient clearance for the handles to be moved in and out with the spring interposed therebetween.

In the operation of the device the handles are spread apart and the jaws engaged over the battery post, the gripping ends underneath the terminal connecter 6. As the handles are now moved toward each other the jaws are moved toward each other and the end of the plunger 11 is brought into engagement with the end of the post 5 through the action of the toggle links connecting the jaws. It is now impossible for the plunger to move forwardly any further as the battery post 5 is a fixed part, and continued pressure applied to the handles to move the jaws inwardly causes the rear end of the jaws and the handles to move inwardly and rearwardly, the jaws retracting relative the plunger so that the whole tool moves rearwardly relative the post 5 and the plunger 11, and the connecter is withdrawn from the battery post. The position assumed in the withdrawal of the connecter is illustrated in dotted outline in Fig. 1. The action of the spring is to normally hold the .plunger in the retracted position.

What I claimis: Y

`l. The combination in a tool of the class described, a pair of crossed handles pivoted together .intermediate their ends, a air of ripping jaws pivoted to said han les, sai jaws also toggled to each other through a plunger -disposed therebetween, and a spring member tov yieldingly hold the plunger inthe retracted position.

2. The combination in a-tool of the class described, a pair of crossed handles pivoted together, a pair of gripping jaws, one pivoted to the end of each handle, a toggle connection between said jaws rearwardly of the ivotal connection of each jaw with the handle, a plunger carried by said toggle connection between said jaws to be project ed forwardly as the jaws are moved toward each other, and yielding means to normally hold the plunger in the retracted posit1on.

` 3. In a battery connecter removing tool, in combination, a pair of pivotally connected handles, a pairrofo posed jaws having inturned gripping en s, one jaw pivoted to each handle, a toggle connection between said jaws rearwardly of the pivotal connection of each jaw with the handle, a fulcrum member extending forwardly between said-jaws from the intermediate pivot point of said toggle connection, said jaws adapted to be retracted relative said fulcrum member when the fulcrum is held against forward movement and the jaws are moved toward each other by the operation of the handles.

4. In a tool of the class described, the

combination of a pair of opposed gripping jaws, a toggle connection between said jaws, a fulcrum plunger pivoted to said toggle connection between said jaws and movable forwardly as the jaws are moved toward each other, operating handles connected with said jaws to move said jaws toward and away from each other.

5. In a tool ofthe class described, in combination, a pair of opposed jaws having gripping ends, a toggle connecting the oppo- .site ends of said jaws, a plunger pivotally supported at the intermediate toggle connection and extending forwardly between said jaws, a pair of operating handles connected to said jaws to move them toward each other and through the operation of the toggle connection to exert pressure forwardly on said plunger.

6. In a tool of the class described, in combination, a pair of cros'sed handles pivoted together, a pair of jaws having inturned gripping ends, one jaw pivoted to each handle, a link pivoted to each jaw rearwardly of its Apivotal connection with the handle, said links pivoted together intermediate said jaws, a plunger pivotally supported between said links to move forward- 1y between the jaws as the jaws are moved toward each other, and a spring to hold the plunger rearwardly toward the pivotal connection of the handles.

In testimony whereof, I sign this specification.y
